这些管子通向靶室&一个三层楼高的大球，这个球上面镶钉着舷窗以让激光通过。
When the 2013 encore , the latest entry in Buick \' s return to relevancy , arrived at my house , I immediately recognized all the traditional Buick styling cues : Waterfall grille , portholes , and tri-shield emblem .
Interior spaces are impressively maximized by the full beam concept , while large hull portholes maximize the natural light in all cabins .

The easier task probably falls to Space Adventures , whose well-tested Soyuz capsules-which have been flying , in one form or another , since the 1960s-require a beefier communications system , larger portholes ( everyone wants a window seat , after all ) and a better heat shield for re-entry . A separate booster rocket will be necessary to break the craft out of Earth orbit .
In general , several die modification methods were chosen to eliminate uneven velocity distribution in the section of bearing exit , such as adjustment of the size , shape and location of portholes , modification of the bearing length and seaming chamber shape .
